چکیده انگلیسی
A high density of nanovoids between 2 and 13 nm in size was produced during the crystallization process when amorphous Al2O3 and WO3, which are 20–30% lower in density than their crystalline phases, were annealed. By contrast, no formation or growth of nanovoids was observed during the crystallization of amorphous TiO2, which has a density 2% lower than its crystalline phase. These results suggest that large differences in density between amorphous and crystalline oxides can be utilized to produce nanoporous structures.
